本產品的文件集力求使用無偏見用語。針對本文件集的目的，無偏見係定義為未根據年齡、身心障礙、性別、種族身分、民族身分、性別傾向、社會經濟地位及交織性表示歧視的用語。由於本產品軟體使用者介面中硬式編碼的語言、根據 RFP 文件使用的語言，或引用第三方產品的語言，因此本文件中可能會出現例外狀況。深入瞭解思科如何使用包容性用語。

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本文提供使用PPP半橋接連線路由和橋接網路的示例配置。

必要條件

需求

本文件沒有特定需求。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

  • Cisco IOS®軟體版本12.2(7b)。

  • 兩台Cisco 2500系列路由器。每個介面至少有一個ISDN BRI介面。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

相關產品

此配置還可以用於以下硬體和軟體版本：

  • 任何序列介面，例如序列、基本速率介面(BRI)、主要速率介面(PRI)等。

  • Cisco IOS軟體版本11.2.

  • 運行上述思科IOS軟體的任何路由器，以及至少一個ISDN-BRI埠。但是，在帶有串列介面的路由器上可以使用半橋功能。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景資訊

網橋將網橋資料包傳送到PPP半網橋，後者將其轉換為路由資料包，並將其轉發到其它路由器進程。同樣，PPP半橋會將路由的資料包轉換為乙太網橋接資料包，並將它們傳送到同一乙太網子網上的網橋。

注意：此配置不會覆蓋兩端的完整網橋。有關此類配置，請參閱跨ISDN橋接文檔。

請注意，在ISDN連線上進行橋接往往會長時間保持連線處於活動狀態（如果不是永久性的）。如果Telco根據連線時間對ISDN計費，則可能會產生非常高的費用。因此，對於擁有無限使用ISDN線路的客戶，建議使用此方案。

注意：介面不能同時充當半橋和網橋。Cisco IOS軟體支援每個乙太網子網最多一個PPP半網橋。

設定

本節提供用於設定本文件中所述功能的資訊。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用命令查詢工具(僅限註冊客戶)。

網路圖表

本檔案會使用以下網路設定：

ppp_half_bridging.gif

組態

本檔案會使用以下設定：

  • 金星

    此路由器被配置為禁用IP路由的完整網橋。任何橋接流量到達時，裝置都會撥號。

  • 土星

    此路由器已配置為半網橋。請注意，此端未設定dialer string、dialer group和dialer list命令。因此，此路由器不會撥號，但會接受來電。這可防止路由器撥打遠端路由器。此處已開啟IP路由。此路由器上未配置完全橋接軟體。PPP半橋接器正在BRI介面上運行，因此show bridge和show spanning-tree等命令不會在此路由器上生成任何輸出。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

  • show isdn status — 顯示ISDN介面的L1、L2和L3狀態。

  • show dialer — 顯示撥號器的狀態和ISDN通道的單獨狀態。

  • show bridge — 在特權EXEC模式下顯示網橋轉發資料庫中的條目類。

  • show interface — 顯示各種介面的狀態，包括串列介面和BRI介面。

  • show arp — 檢查ARP對映。ARP是用於將第2層位址（MAC位址）對應到第3層位址（IP位址）的通訊協定。

  • show spanning-tree — 顯示路由器已知的生成樹拓撲。

注意：發出debug命令之前，請參閱有關Debug命令的重要資訊。

  • debug dialer — 指示檢測到相關流量以及撥號啟動的時間。

  • debug isdn event — 指示ISDN介面的使用者端發生ISDN活動，類似於debug isdn q931。

  • debug isdn q931 — 提供本地路由器（使用者端）與網路之間的ISDN網路連線（第3層）的呼叫建立和拆除資訊。

  • debug isdn q921 — 顯示路由器在其ISDN介面的D通道(LAPD)上發生的資料鏈路層（第2層）訪問過程。

  • debug ppp negotiation — 執行PPP選項和網路控制協定(NCP)引數的協商。

  • debug ppp authentication — 允許交換質詢身份驗證協定(CHAP)和口令身份驗證協定(PAP)資料包。
